The MultEQ algorithms require acoustical information from multiple locations within the listening area in order to create the appropriate room correction filters for each loudspeaker and subwoofer in the system. The first measurement is used to determine the distance and level of each speaker and it should be taken in the center-most position of the listening area. After that, it is recommended to take 6-8 more measurements throughout the listening area.

The order of the measurements after the first one does not matterIt is very important to avoid extreme positions including up against the back wall or too far outside angle spanned by the front Left and Right speakers. Taking measurements in these positions will cause MultEQ to make unnecessary adjustmentsMeasurements should be at ear height with some small vertical variation.

I don't know - I think that what I did is quite OK according to them...

Good call on going for another calibration. That's awesome it's sounding better. So with Audyssey, you get to do the calibration from 6 different listening positions? That's pretty incredible. I only saw my dad do it from 1 listening position through MCACC on his Pioneer Elite.

I've just been reading some more about subwoofers...lol I just can't help myself. I like something that quakes hard.

What is everyone's opinion on Submersive? I just stumbled across them. I'm reading a good handful of people have went from SVS to submersive, but no one really goes from submersive to SVS.

MCACC will also allow you to do a multi-point calibration. I haven't tried it yet because I always sit in the same spot but the option is there.

Not the same thing. Audyssey does 6-8 positions for the same seating position. MCACC does 1 position for up to 6 seating positions.

Not sure exactly but you mean but with MCACC multi-point you move the microphone to different seating positions during the calibration.
